I’m a bit confused the text on this map because the jokes appear to be AD&D related as opposed to D&D B/X or BECMI. This in turn reminds me that at the time in the shops (in the UK at least) AD&D seemed to eclipse the D&D box sets especially in terms of the availability of modules (although this one was packaged in with the Expert rules). Also there was great snobbery in groups in my locality against the boxed games, so I’m always intrigued to see how these things are celebrated in retrospect. But hey, looking back we just sort of lump all of this stuff together now, which is okay I guess, unless you’re a purist. ;)
